Hello there,
regarding the problem using language specific characters,
like German ��� in filenames or command line characters,
mono (0.28) only supports UTF-8 character encoding for
filenames and command line parameters
( see: http://bugzilla.ximian.com/show_bug.cgi?id=30781 ).
Therefore you will have to enable UTF-8 mode on the console (e.g. with:
echo -e "\033%G"), if you want to call the following C# programm:
// ---------------- 8< ------------------ >8 ---------------------
using System;
using System.IO;
namespace CreatePath
{
public class CreatePath
{
public static void Main(string []args)
{
Directory.CreateDirectory(args[0]);
}
}
}
// ---------------- 8< ------------------ >8 ---------------------
with:
$mono CreatePath.exe Dir�������001
otherwise you will get the following exception:
Unhandled Exception: System.ArgumentNullException: Argument cannot be null
Parameter name: path
in <0x00036> System.IO.Directory:CreateDirectory (string)
in <0x00020> CreatePath.CreatePath:Main (string[])
.
On our linux environment we partly use "[EMAIL PROTECTED]" for language encoding
(LC_CTYPE = [EMAIL PROTECTED]), that works fine with Samba 2.2.7a, which does not
support UTF-8. I did a small patch in unicode.c (mono/io-layer/unicode.c)
and unicode.h (mono/io-layer/unicode.h) to test, whether it works with locale encoding
for directory-/filenames and it does.
If you use the following conversion functions (primary the first and
second):
/* ---------------- 8< ------------------ >8 --------------------- */
#include <glib.h>
#include <glib/gconvert.h>
gchar *_wapi_unicode_to_locale(const gunichar2 *uni)
{
GError *error = NULL;
gchar *res = NULL;
gchar *utf8_ret;
utf8_ret = g_utf16_to_utf8 (uni, -1, NULL, NULL, &error);
if (utf8_ret)
{
res = _wapi_utf8_to_locale (utf8_ret);
}
g_assert(!error);
return res;
}
gunichar2 *_wapi_locale_to_unicode(const gchar *locale)
{
GError *error = NULL;
gunichar2 *res = NULL;
gchar *utf8_ret;
utf8_ret = _wapi_locale_to_utf8 (locale);
if (utf8_ret)
{
res = g_utf8_to_utf16(utf8_ret, -1, NULL, NULL, &error);
}
g_assert(!error);
return res;
}
gchar *_wapi_locale_to_utf8(const gchar *locale)
{
GError *error = NULL;
gchar *res;
gsize bytes_written = 0;
res = g_locale_to_utf8 (locale, -1, NULL,
&bytes_written, &error);
g_assert(!error);
return res;
}
gchar *_wapi_utf8_to_locale(const gchar *utf8)
{
GError *error = NULL;
gchar *res;
gsize bytes_written = 0;
res = g_locale_from_utf8 (utf8, -1, NULL,
&bytes_written, &error);
g_assert (!error);
return res;
}
/* ---------------- 8< ------------------ >8 --------------------- */
it should work for both, reading command line parameters and reading / creating
directories and files with any locale character encoding
(even UTF-8).
It would be great, if such a conversion could be implemented in mono.
Thanks a lot,
Uwe Oertel
